Another important topic of discussion surrounding Au. africanus is the level of variation seen between individuals of this species. The variation in many characteristics such as molar size and facial structure is larger than that seen in any living apes. This point has led some scientists to believe that the species Au. africanus actually consists of two separate species. These differences still stand even when considering Au. africanus to be a very sexually dimorphic species (a species with two body forms and/or sizes, one male and one female, a trait that occurs in many primates, including humans). If Au. africanus was actually two species, some of our hypotheses about the relationship of Au. afrricanus to other hominins could be refined.
